To repair a crooked, broken nose and remove a hump or bump on the dorsum (bridge) of the nose, a rhinoplasty may be performed. An alternative to surgery may be to use injectable filler materials to camouflage the issues which are of concern to you. This requires much knowledge, training and skill to minimize the risk of complications. Therefore, I suggest you seek consultation from a board certified plastic or facial plastic surgeon.
Trauma to the nose can create a fracture of the nasal bones with displacement and make the hump appear larger. To remove the hump, it must be shaved down. To straighten the nasal bones, osteotomies are performed to straighten them. Fixing a broken and crooked nose is a surgical procedure, not something that can be taken lightly and done in the office with an injection.
